Product Description
AMSOIL Heavy-Duty Antifreeze & Coolant is the best option for mixed fleets of both heavy-duty applications & passenger-vehicles that want to use one antifreeze/coolant. AMSOIL Antifreeze/Coolant is a poly-organic acid formulation that does not contain inorganic acid salts (phosphate, nitrate, nitrite, silicate, borate, amine) found in conventional and hybrid organic acid (HOAT) antifreeze/coolants. These materials are responsible for almost all scaling issues in cooling systems, and they can also precipitate to form scale if the antifreeze/coolant inhibitor system is at the wrong pH or mixed with incompatible products. AMSOIL Antifreeze/Coolant virtually eliminates scaling problems.

AMSOIL Heavy-Duty Antifreeze & Coolant features

• Pre-mixed 50/50 with high-purity water.
• Fully formulated: DOES NOT require the use of supplemental coolant additives (SCAs) or extenders.
• All-organic formulation is further enhanced with anti-scalant, anti-fouling and water-pump lubrication additives.
• Phosphate, nitrate, nitrite, silicate, borate and amine-free.
• Boil-over protection up to 265°F with a 15 psi radiator cap.
• Freeze protection down to -34°F.

Long-Life Formulations
AMSOIL Antifreeze/Coolants do not contain inorganic salts that deplete over time and turn into scale deposits. Their unique blend of organic acids provide durable and long-lasting protection of cooling system components. Heavy-Duty Antifreeze & Coolant can be used for 600,000 miles, 12,000 hours of operation or six years, whichever comes first, in heavy-duty and off-road applications.

Compatible With Other Fluids
AMSOIL Antifreeze/Coolant is compatible with all ethylene and propylene antifreeze and coolant colors, as well as all plastics and elastomers (hoses, gaskets, etc.) found in cooling systems. However, mixing propylene and ethylene glycol formulations can make it difficult to predict freeze protection. If mixing for top-off is unavoidable, it is recommended to flush the cooling system at the next convenient opportunity.

SERVICE LIFE
Protection up to 600,000 miles, 12,000 hours or 6 years, whichever comes first. Heavy-Duty Antifreeze & Coolant can be used in non-heavy-duty applications, but with a drain interval of 150,000 miles or five years, whichever comes first.

Directions for Use
• Do not add water.
• Do not remove radiator cap when engine is hot.
• Antifreeze/coolant (new or used) is hazardous. Clean up and dispose of properly following local regulations.
• Check and maintain coolant level at every oil-change interval.
• Check owner's manual for additional maintenance and top-off guidelines.
